[Eeglablist] question for overlapping in Spectopo()

Dear Arno,
Since it says [integer], does this imply that if I want to have a 50% overlap, I need to pass "'overlap',50" instead of "'overlap', 0.5" to the function? Or other number format?
Thanks!

Dear Makoto,
Yes this is what it means.

Does this mean by default there is not overlap in spectopo()? I guess it uses windowing function. Windowing with no overlap?

Dear Makoto,
There were some discussions in archives about overlapping for Spectopo(), but no confirmation was reached. So I hope to ask this again:
The pwelch() function in Matlab has a default overlapping of 50%. But Spectopo(), which uses pwelch() function, has the following description in help file:
'overlap' = [integer] window overlap in data points {default: 0}
So in the end do we need to pass the overlap value pair to Spectopo()?
Thank you!
